Allen-Bradley 193-ESM-IG-30A-T – Ethernet/IP Smart Motor Controller I/O Expansion Module | E3 Plus Platform
Engineering Background
The Allen-Bradley 193-ESM-IG-30A-T is a dedicated I/O expansion module engineered for the E3 Plus Electronic Overload Relay platform. Designed by Rockwell Automation, this module extends the native I/O capability of the E3 Plus relay by adding isolated digital inputs and outputs accessible over an Ethernet/IP network — enabling seamless integration into modern ControlLogix, CompactLogix, and GuardLogix control architectures without additional gateway hardware.
Product Positioning
Targeted at OEM machine builders and plant engineers who require deterministic, network-transparent motor protection with distributed I/O expansion, the 193-ESM-IG-30A-T eliminates the need for standalone I/O modules in motor control center (MCC) applications. Its compact DIN-rail form factor and plug-in connectivity to the E3 Plus relay make it the preferred choice for high-density MCC panel designs where space and wiring cost are critical constraints.

System Architecture & Signal Flow
The 193-ESM-IG-30A-T connects directly to the expansion port of the E3 Plus Electronic Overload Relay (catalog series 193-EC*). The module bridges the relay’s internal motor protection data — including current measurement, trip status, and thermal model state — with the plant’s Ethernet/IP network. The PLC (ControlLogix / CompactLogix) communicates with the module via Class 1 implicit I/O messaging, receiving real-time motor status and sending output commands within a single network scan. Isolated digital inputs on the module accept field device signals (e.g., limit switches, pressure switches) and forward them to the PLC tag database without additional I/O modules.
Signal Flow Summary: Field Device → Isolated Digital Input → E3 Plus Internal Bus → Ethernet/IP Network → PLC I/O Tag → Studio 5000 Logic

Technical FAQ
Q: Is the 193-ESM-IG-30A-T compatible with all E3 Plus relay variants?
A: The ESM-IG expansion module is compatible with E3 Plus relays in the 193-EC* series. Verify the specific relay catalog number against Rockwell Publication 193-UM002 for confirmed compatibility.
Q: Can this module be used with a CompactLogix controller?
A: Yes. The module communicates via standard Ethernet/IP CIP protocol and is fully compatible with CompactLogix, ControlLogix, and GuardLogix platforms running Studio 5000 Logix Designer.
Q: What is the maximum cable length for the Ethernet connection?
A: Standard IEEE 802.3 Ethernet — up to 100 m per segment using Cat5e or Cat6 cable. Fiber optic media converters can extend this for larger plant layouts.
Q: Does the module support explicit messaging (MSG instruction)?
A: Yes. In addition to Class 1 implicit I/O, the module supports Class 3 explicit messaging for configuration and diagnostic reads from the PLC ladder logic.
Q: What happens to the outputs if the Ethernet connection is lost?
A: The module enters a configurable fault state — outputs can be set to hold last state or de-energize, depending on the connection configuration in Studio 5000.
